Power Supply: 16 Vdc 2.5 Amp
The 110 Vac outlet must be dedicated to the unit only. This outlet
should be wired back to its own 10 Amp minimum circuit breaker.
This will prevent two problems:
• Other equipment cannot introduce spikes, noise, surges, or dips
into the power circuit.
• The unit's operation will not be affected if any other equipment
develops a short circuit across the power line.
